permissions - is this the best approach?

[Chinook <chinook.nr@tds.net>]

I've set up a Linux and Mac zeroconf (netatalk) LAN. On the Linux box 
(Debian Etch) I have a shared directory for passing files to/from the 
Linux box, that is accessed from the Mac (while AppleTalk/zeroconf 
allows a peer-to-peer network model, netatalk only provides for a Mac to 
"see" a Linux system but the Linux system can't "see" a Mac for file 
sharing).

As root on the Linux box I created a new user "lanshare" accepting 
standard permissions for the /home/lanshare directory
owner: rwx group: r-x others: r-x
I also added to the "lanshare" group the other Linux users that I want 
to be able to use a shared directory.

Then I logged in as "lanshare" and created the folder "public" in 
/home/lanshare/. For this "public" folder I modified the permissions to
owner: rwx group: rwx others: ---
and I set the sticky bit.

The idea is to allow various users on the Linux box the ability to 
create and delete their own files in /home/lanshare/public and to 
read/copy any files therein. The Mac will create and delete files 
therein as the user "lanshare."

This seems to work as intended, but I'm wondering if such is the best 
way to handle the setup?

Thank you,
